Removal of bacterial pathogen from wastewater using Al filter with Ag-containing nanocomposite film by in situ dispersion involving polyol process

► Ag/Al(OH)3 mesoporous nanocomposite film was in situ-deposited on Al foam filter. ► The synthesized Ag NPs showed two distinct morphologies due to the Al(OH)3 film. ► The Ag/Al(OH)3 filter showed good bacteria removal rate within a short contact time.
